PURPOSE:To make the sizes in width and thickness directions with respect to a longitudinal directional uniform by providing mold varying devices for forming respective ingots and a mold positioning device for setting the sizes in the width or thickness direction of the respective ingots to a casting device and forming the respective ingots at the width or thickness sizes slightly larger in the central part than in the end parts. CONSTITUTION:The length of an ingot 1 is measured and a target value is operated by the data from a setter 17 for cutting length of slabs, a setter 18 for thickness of slabs, a setter 19 for width of slabs, a setter 20 for thickness in end parts, a setter 21 for width in end parts and a setter 22 for length of end parts as well as the count outputs of a counter 15 to which the outputs of a pulse oscillator 16 mounted to pinch rolls 10 are supplied. The target value is applied to a mold positioning device 13, which adjusts the width and thickness of the ingot 1 automatically. The ingot 1 is formed to the sizes in the width and thickness in the central part thereof slightly larger than in the end parts thereof. |
